| 摘 要： | 溶液吸附法测定活性炭比表面积实验教学,对于学生更好理解、掌握相关概念和原理,培养学生分析问题、解决问题能力极为重要。但教学过程发现由于学生对活性炭、亚甲基蓝溶液浓度及被吸附取向的相关问题理解模糊或错误,致使实验结果偏差较大。通过实验方法、内容调整,结合量化计算及学科前沿知识对该实验进行了改进,既丰富了实验内容,也保证了学生的实验效果。

| Abstract: | The experimental teaching of“specific surface area determination of activated carbon by solution adsorption method”is very important for students to better understand and master concepts and principles,and cultivate ability to analyze and solve problems.However,it was found that the experimental results were very poor based on the the students′understanding vague or wrong of the concentration of activated carbon,methylene blue solution and the adsorption orientation.The experimental teaching is improved by adjusting the experimental method and content,combining with quantitative calculation and subject frontier,which not only enriches the experimental content,but also guarantees the experimental effect of students. |
